British Prime Minister Gordon Brown has apologised for abuses of politicians expenses, which included claims for dog food and light bulbs.The revelations by a leading daily paper have embarassed the government and opposition, and heaped pressure on an already embattled Brown. Brown said: “I want to apologise on behalf of politicians of all parties for what has happened in the events of this last few days” With their own members under scrutiny the Conservatives have not been able to capitalise too much on the affair. But their leader joined Brown in calling for change. David Cameron said: “Individually members of parliament have got to explain why they claimed what they claimed and set that out. Collectively, I think we’ve all got to put our hands up and say this is a system that we operated and used and is just absolutely not right, and has got to be change”. With the recession hitting many people hard there has been widespread public anger over the expenses claims, which included paying workmen to replace 25 light bulbs at one MP’s London home.
